AUTOMATIC .REEL-TRANSFERRING MECHANISM: FOR PAPER-WINDING MACHINES.

Application ifiled February 5, 1926, Serial No.

This invention relates to an automatic transfer mechanism for paper winding machines.

In high speed paper making machines, which deliver a web of paper at a rate of 300 or even 1100 feet per minute, the trans-- ference of the web from a winding reel which has been filled to afresh empty one is a matter of difficulty, often involving a considerable Waste of paper, and often causing areel to be wound with a soft centre, which leads to difiiculty'in subsequent processes.

' With a view of lessening the time occupied in the transfer, it is usual to support an empty reel in close proximity to the reel which is being filled, and to-provided means for substituting it quickly for the filled reel. The paper web is fed to the winding reel over a drum, the reel resting on the paper on'the drum, and an empty reel is brought into action by shifting it from a waiting position in which it is out of contact with the paper into a position in which it contacts with the paper, and then severing the web of paper and causing it to wrap upon the fresh reel. An earlier invention of the present applicant provides for performing these operations not only rapidly,

but to a large extent automatically, the

movement of the filled reel due to the accumulation of paper upon it, or movement resulting from the removal of the filled reel, being arranged to bring about the substitution of a fresh reel and if suitable preparations have been made the wrapping of the paper upon it.

The object of the present invention is to .provided improved means for bringing about the severance of the paper and the wrapping of it on an empty reel wholly automatically. According to the invention this is effected by the aid of a jet of water. A suitable nozzle is supported near the winding reel, and is directed towards the position the reel will occupy at the. instant it is desired to transfer the web to it; and the movements of the winding machine mechanism preceding or accompanying the shifting of a new reel into winding position are utilized to open a valve to admit waterin predetermined quantity to the nozzle.

The invention further provides for adjusting the time at which water issues from the nozzle in relation to the instant at which the valve is operated, and also for rapidly 86,215, and in Great Britain February 5, 1925.

closing the valve after the desired interval, in order that water may not drop slowl and uselessly from the nozzle upon the we and cause breaks.

The invention consists in the combination and arrangement of partsset forth in the following specification and particularly pointed out in the claims.

Referring to the drawings Figure 1 is a side elevation of one embodiment of my invention.

As is usual in paper winding mac iines of this type, the web of paper is fed to a reel 1 over a drum 2 which is rotated at a pcripheral speed slightly higher than the speed of delivery of the web; and the reel 1 while being wound is carried in bearings 3 in a rocking frame 4 pivoted at 4: to the frame of the machine, which swings slowly ut ward as paper accumulates on the reel.

An empty reel 1 is placed in readiness on the nearly horizontal part of two supporting brackets 6, one on each side of the machine; and when the filled reel is about to be removed, the empty reel is pushed on the sloping part 7 of the brackets 6. It then rests against the cams 8 which are pivoted at 9 upon the rocking frame 4, and the outline of which forms with the surface 10 of the rocking frame a continuous curve leading to the bearings 3, the first portion of the curve being concentric with the pivot of the rocking frame. On the removal of the filled reel which is accomplished by a hoisting crane m a "Well-known manner and 110 secured upon the rocking frame.

as disclosed in my British Patent No. 223, 273, dated @ctober 15, 1924, Machine for winding paper webs, the rocking frame l falls back under gravity, cushioned by the dash pot ll, towards the drum 2, and the new reel 1 moves down the surface 7 into the bearings 3 and immediately afterwards comes into contact with the web of paper on the drum 2, which is still being'wound upon the filled reel 1 by virtue of its continued rotation due to momentum while still held suspended by said. hoisting crane.

Any convenient part of the movement of the rocking frame may be utilized for the purpose of the present invention, that is to bring about the spraying of water upon the new reel 1*. In the construction illustrated part of the inward movement of the frame is utilized.

There is provided preferably on the rear side of the machine, a nozzle 12, directed at a slant towards the position the reel occupies immediately before it comes in contact with the drum. The nozzle is so placed (or several nozzles may be so provi led) that when water is vigorously eje-zited from it (or them) the reel will be wetted through substantially its whole length. Water is supplied by the pipe 13 in which is a valve l l normally held closed by a spring 15. The stem of the valve may be made with a head 16 so that it can be opened by hand when required. lts automatic openin is brought about by a lever 17 pivoted at 18, which bears at one end upon the valve stem and at the other end is linked to a dash pot 19 seen in further detail in Figure 2. llhe lever 17 is slotted, and there passes through it the hooked end of a rod 20 which is forked at 21 and engages over and can slide to and fro upon the pivot of the rocking f'ame 4. At its end the rod carries a stud 22 in position to be engaged by each of two cams 23 and 24 The adjustable stop 25 in the lever 17 abuts upon the rod 20 when the lever is sulficiently turned. A spring 26 is compressed by the end of the outward movementof the rocking frame, and serves to give it an initial inward impulse when the filled reel .is removed.

Since the turning, 0d of the water as well as the turning on of the water is required to result automatically from the. motion of the rocking frame, it is obvious that in the present arrangement which utilizes an inward movement of the frame for the purpose, the water must be turned off just before or just as the frame reaches the end of its inward movement, and therefore the water must be turned on a short time before the end of the movement. But the water is desired to issue from the nozzle 12 quite at the end of the movement, that closed.

towards its completely closed position there would be interval during which water passed through the valve at a. very slow rate, insufiicient to cause a. vigorous jot at the nozzle 12, and consequently it would drip from the nozzle upon one part of the rec, needlessly wetting the web and causing breaks. To prevent this the dash pot 19 is designed as shown in Figure 2, the lower part of its bore beingenlarged; so that as the piston nears the end of its stroke the resistance of the fluid suddenly ceases owing to its escape around the piston, and thus the valve is quickly closed by the s 'n'ing 15 after being held wide open for the desired length of time.

The action of the apparatus is as follows :As the rocking frame moves in ward after the removal of the filled rccl, under the action of spring 26 and gravity resisted by the dash pot 11, com 23 engages stud 22 and pulls the rod 20, which through its hook turns the lever 17 and opens the valve 14. The water first .lills the reservoir 27, and only when that is done can it issue from the nozzle 12. By adjustment of the size of the reservoir it is easy to adjust the exact instant at which the water issues. Quite near the end of the movement, for instance when the frame has reached the position indicated in dotted lines, the cam engages the stud 22 and pulls the rod 20 further, so further turning the lever 17 and causing the stop 25 to abut upon the rod 20 and disengage its hook from the lever 17. The lever at once liogins to return and the valve to close under the action of the spring 15 resisted by the dash pot 15), but the valve opening is not at first constricted. ll hcn the piston ol' the dash pot reaches the enlargement of its cylinder the valve is suddenly completely The dash pot 19, therefore. (lcl i'- mines the length of time during which \\':ll(l shall issue from the nozzle 12. and it is made adjustable in position for the purpose of altering this time.

A small drain cook 137 permits a constant leak from the reservoir 27, so that the reservoir is emptied by the time the next reel is filled and the operation has to be repented. Instead of this constant le: it, a drain cock may be provided which opened automatically by the rocking frame on its outward movement and closed prior to the cycle of operations connected with. the transference of the web to a new reel. as illustrated in for) hill

tlil

essee? Fig. 4, in which a lever 38 fast to the pivot 4 is connected by a rod 39 to an arm 40 which operates the leak cock 3?.

The water flung upon the reel 1 is immediately carried downto the paper and wets it, with the double result that the web is severed from the part still being wound upon the removed reel and that it adheres to the new reel and begins to wind upon it.

ln case of a breakage of paper, or for other reasons, it may be necessary to cause the above cycle of operations to occur independently of movement of the frame 4. For this purpose a cam 28 is loosely mounted on the pivot ot the frame, as seen in Fig. 3, and providedwith a handle 29 by which it may be rotated; at single rotation of this cam by hand brings about the same results as a normal return movement of the rocking trame.

l igure shows the invention applied to another known t'ormot' paper winding machine of the same general type. .lnthis case the empty reel 1 is supported in arms 30 which can be rocked by hand by means of the pinion 31 and segment 32. The empty reel 1 is placed in the position shown in dotted lines while the preceding reel 1 being filled. When the filling is complete the arms 30 are rocked to the'position shown in full lines so that the reel 1 is brought into contact with the paper web. It is at this instant that the web should wound upon the new reel.

For this purpose, according to the present invention, the arms 30 are fitted with a tail piece 33 which engages a gravity actuated tumbler 36 pivoted on a valve lever 34 when the arms 80 are rocked as above described, and opens a valve 34' against the action of a spring "When the paper has firmlywrapped itself upon the new reel 1 the arms 30 are turned back by hand so as to bring the new reel into the bearings of the usual rocking frame 4. This movement of the arms should not atloct the valve 34', the closing of which may be controlled in the manner already described. For this reason the valve is fitted with the gravity-actuated tumbler 36, so that the tail piece 33 can move idly past it in one direction.

The particular mechanism employed to actuate the water valve orvalves may be considerably modified. For instance it is not necessary that the valve shall be operated by the moving parts of the reeling mechanism provided its operation is caused at the proper time, as for example, the valve may be opened and closed by means of a cam which can be caused to malre a single revolution by the engagement of a clutch which connects it to the mechanism driving the drum The function of the rocking frame 4, in this case, is only to pat the clutch in be severed and 4tis again operated by the rod 44.

action, whereupon the cam is rotated and effects the desired cycle of operations at the desired instants of time and such a mechanism is illustrated in Figs. 6, 7 and 8, in which an arm. 41 is fastened to a rocker pivot 42 to which a rocker frame 43 is tastened and a connecting rod 44 is fastened to said arm 41. The rocking of the frame 423 through the pivot 42 imparts a rocking movement to the arm 41 and a rcciprocatory movement to the connecting rod 44. A shoulder 45 is provided upon the outer end of the connecting rod 44 which, at the proper time, engages a awl 46 causing the same to be lifted out o engagement with a clutch guide plate 47 and this allows a spring 48, see Fig. 8, to'pull the guide plate 47, together with a roller 49 up the incline 50 of a fixed clutch member 51 and thus bind a sprocket wheel between the fixed clutch member 51 and a fixed cam 53, thus causing the cam shaft 54 to revolve and operate a water valve 55 through a'belhcrank lever 58. The rod 44 after lifting the pawl 46 continues its travel toward the left, Fig. 6, until it arrives upon a pin 56 which allows the pawl 46 to return to the position shown in Fig. 6, so that as the clutch guide plate 47 comes in contact with it, its movement is arrested, thus carrying the roller 49 dowr into a larger part of a slot 57 in the fixed member 51, wl'icreupon the cam shaft stops and will rest in this position until the pawl The clutch guide plate 4-7 is connected to the fixed clutch member 51 by the spring 425 which operates to force the roller 49 up the slot 57 as long as it is not prevented from so doing by the action of the pawl 46.
